Does he like me? Is he just too shy? What should I do?

This guy's really shy or something? Oh we are strangers, work in same company but different departments. I have no clue what his name is. But every time I'm in the break room and he's there he'll gaze at me as im walking in. Like a in aw gaze. Once I saw him from the corner of my eyes walking towards me, he stopped 10ft away and hesitated turned back around and walk back away. My group sits near his group. He's always facing away from me but always glance at me. I don't remember when this started but now that i see it I realize he gets really red when i sit towards him. So I'm guessing he likes me from all of this. Right? He's just super shy or something? Why is he so shy? These are good signs right?

I don't know if I like him yet. Cause we never talked before.
